Hud 11:12

Perhaps you may disregard some of what is revealed to you [O Prophet][6], and may feel distressed because they say, “Why has not a treasure been sent down to him, or why has not an angel come with him?” You are only a warner[7], and Allah is in charge of all things.

[6] i.e., things that they may find arduous to act upon. [7] The Prophet (ﷺ) is tasked only to deliver the message, not to fulfill their whimsical wishes.

Then would you possibly leave [out] some of what is revealed to you,[550] or is your breast constrained by it because they say, "Why has there not been sent down to him a treasure or come with him an angel?" But you are only a warner. And Allāh is Disposer of all things.

[550] Knowing of the Prophet's difficulties, Allāh (subḥānahu wa taʿālā) urges him to patience, certain that he would not fail to convey the message in its entirety.

12. So perchance you (Muhammad صلى الله عليه و سلم) may give up a part of what is revealed unto you, and that your breast feels straitened for it because they say, "Why has not a treasure been sent down unto him, or an angel has come with him?" But you are only a warner. And Allâh is a Wakîl (Disposer of affairs, Trustee, Guardian) over all things.

A likely thing, that thou wouldst forsake aught of that which hath been revealed unto thee, and that thy breast should be straitened for it, because they say: Why hath not a treasure been sent down for him, or an angel come with him? Thou art but a warner, and Allah is in charge of all things.
